It wasn't until recently that women’s baldness became an OK object of discourse. It wasn't very long ago that girls did everything they could to hide the undeniable fact they had thinning hair (or that they were absolutely losing it). Not only has it become OK to discuss, there also are more treatment methods available for girls than there are for men.
The hair loss industry isn't one that provokes great confidence in the majority of people. I must admit this is perfectly comprehensible given the damage due to the many rogues and charlatans who've abused the trust of too many vulnerable folks – folk who've received worthless and even threatening products or information in exchange for their hard earned money. The ultimate result is the prevalance of a stigma the industry is unlikely to shrug off.
